Fatigue In Collegiate Aviation, Erik Levin, Flavio Coimbra Mendonca Mr, Julius Keller, Aaron Teo

International Journal of Aviation, Aeronautics, and Aerospace

Flight training has received little attention in fatigue research. Only transfers of knowledge gained in commercial and military aviation have been applied to general aviation without bridging the gap to the training environment. The purpose of this study was to assess collegiate aviation students’ perceptions of lifestyle and mitigation strategies related to fatigue. Participants were recruited from a Midwestern university’s accredited Part 141 flight school and a partner fixed base operator (FBO). The researchers of this study used a survey questionnaire to gather quantitative and qualitative responses. The majority of participants (68%) had logged less than 250 flight hours and …

Wild Entanglements: Exploring The Visions And Dilemmas Of ‘Renaturing’ Urban Britain, Cara Louisa Clancy

School of Geography, Earth and Environmental Sciences Theses

In a rapidly urbanising world, where lands are increasingly repurposed for human endeavours, where seas and rivers carry the weight of mounting plastic, where species extinction is a common theme and where the effects of global climate change are a daily reality, there has never been a more pressing need to rethink nature-society relations and environmental ethics. This thesis draws insights from two cases of urban renaturing in Britain (London and Plymouth) to explore critical issues in contemporary environmental practice, including what matters for humans and nonhumans in such endeavours. Renaturing is here understood as an intentional, reflective attempt to …

Development Of Biomarker-Based Proxy Methods For Reconstructing The Late Quaternary Sea Ice History In The Barents Sea, Deniz Can Koseoglu

School of Geography, Earth and Environmental Sciences Theses

Application of the sympagic diatom-produced, C25 highly branched isoprenoid (HBI) termed IP25 to paleo-sea ice reconstruction has confirmed its utility as a qualitative seasonal sea ice proxy. Combination of IP25 and a pelagic biomarker into the Phytoplankton-IP25 index (PIP25) has facilitated more detailed, semi-quantitative descriptions of sea ice conditions. Further work is motivated by challenges inherent to univariate methods (such as PIP25), and the availability of multiple HBIs characteristic of ice algal and pelagic production within sedimentary archives. This study investigated the potential of incorporating multiple biomarkers to characterise contrasting sea ice and productivity conditions in the contemporary Barents Sea, …

Time Of Detection As A Metric For Prioritizing Between Climate Observation Quality, Frequency, And Duration, B. R. Carter, N. L. Williams, W. Evans, A. J. Fassbender, L. Barbero, C. Hauri, R. A. Feely, A. J. Sutton

Marine Science Faculty Publications

We advance a simple framework based on “time of detection” for estimating the observational needs of studies assessing climate changes amidst natural variability and apply it to several examples related to ocean acidification. This approach aims to connect the Global Ocean Acidification Observing Network “weather” and “climate” data quality thresholds with a single dynamic threshold appropriate for a range of potential ocean signals and environments. A key implication of the framework is that measurement frequency can be as important as measurement accuracy, particularly in highly variable environments. Pragmatic cost-benefit analyses based on this framework can be performed to quantitatively determine …

Brexit... A Lifetime Of Purgatory For The Uk's Environmental Laws - Or Is There A Stairway To Heaven?, Philip Connor

The Plymouth Law and Criminal Justice Review

This paper considers the prospect that the United Kingdom's decision to withdraw from the European Union may have a detrimental effect on its environmental protections. Brexit may provide the opportunity to pursue a more environmentally focused agenda, but it is argued that the UK's plan to transpose EU legislation underestimates the complexity of the task and that the UK lacks the resources to replicate the system it currently enjoys. On this basis it is thought that a reordering of environmental law is more likely than a radical re writing of it.

Socio-Legal Research: Looking Beyond Black Letter Law In The Context Of Birth Mothers' Rights In Adoption Proceedings, Lisamarie Deblasio

The Plymouth Law and Criminal Justice Review

This article explores the experiences that birth mothers face in adoption proceedings within a socio-legal context. With analysis of data from interviews with 32 birth mothers synthesised with the relevant provisions of the Adoption and Children Act 2002, it is argued that ingrained unfairness and a lack of accountability exists in the legal and administrative system where birth mothers' rights are concerned. Analysis extends to the social problems of blame and stigmatizing of birth mothers which originates from those agencies involved in the adoptions. It highlights the perspectives and voices of birth mothers, who are seldom the focus in leading …

Alternatives To The Common Fisheries Policy? The Future Of The Uk's Fisheries Post-Brexit, George Cass

The Plymouth Law and Criminal Justice Review

The Common Fisheries Policy (CFP) of the European Union has faced problems relating to sustainability since its conception. Subsequent reforms have offered some limited means of mitigating these problems yet ultimately they have not been adequately addressed and continue to cause critical damage to the European fisheries. Sound scientific advice has been continuously ignored resulting in catches in excess of the Total Allowable Catch (TAC), further compounding depleted stocks and reducing the chances of recovery. Despite the latest reform in 2013, European fisheries remain in a perilous condition. Brexit creates an opportunity for the UK to develop its own fisheries …

The Harm Of Child Removal, Shanta Trivedi

All Faculty Scholarship

When the state proves or even merely alleges that a parent has abused or neglected a child, family courts may remove the child from the parent’s care. However, research shows separating a child from her parent(s) has detrimental, long-term emotional and psychological consequences that may be worse than leaving the child at home. This is due to the trauma of removal itself, as well as the unstable nature of, and high rates of abuse in, foster care. Nevertheless, the child welfare system errs on the side of removal and almost uniformly fails to consider the harms associated with that removal. …

Menstrual Justice, Margaret E. Johnson

All Faculty Scholarship

Menstrual injustice is the oppression of menstruators, women, girls, transgender men and boys, and nonbinary persons, simply because they menstruate. Acts of menstrual injustice occur every day in the United States. The narrative of menstruation is that it is a taboo, shameful, and that menstruators are dirty, impure, even dangerous. Menstruation has been shunned generally from public discourse as a result. This narrative negatively impacts menstruators. Menstruators are essentialized as women, often of means, excluding transgender men and nonbinary persons, and menstruators who experience poverty or are young. Menstruating workers, especially low-wage workers, are harassed, penalized, or fired for heavy …

Critical Bicultural Masculinities: Reframing Community College Success Among Latino Immigrant Male Students, Rene Lozano Esquivel

LMU Theses and Dissertations

By employing critical narratives, this qualitative study examined the lives of Latino male immigrants and their educational experiences in the California community college system. Seven Latino male immigrants matriculated at a community college participated in the study. The study utilized Critical Bicultural Theory and Latino Masculinity Theory frameworks to analyze the male students’ narratives. Findings speak of their unique racialized and gendered experiences as they navigate their community college educational experiences. This study contributes to the field by identifying what Latino immigrants need to co-construct their own educational success in a way that employs their strong familial and cultural knowledge. …

Beyond Colonizing Epistemicides: Toward A Decolonizing Framework For Indigenous Education, Samuel B. Torres

LMU Theses and Dissertations

American schooling and Indigenous peoples share a coarse relationship mired by devastating periods of forced removal, indoctrination, and brutal assimilation methods. Over the course of more than a century of failed education policy—though often veiled in good intentions—Indigenous peoples have yet to witness a comprehensive Indigenous education program that fundamentally honors the federal trust responsibility of the United States government. On the contrary, with a contemporary approach of apathy, invisibility, and institutionalization, it is not difficult to see the legacy of settler colonialism continuing to wield its oppressive influence on Indigenous communities. Wolfe’s (2006) claim that “invasion is a structure, …

A Global 3‐D Ocean Model For Pcbs: Benchmark Compounds For Understanding The Impacts Of Global Change On Neutral Persistent Organic Pollutants, Charlotte C. Wagner, Helen N. Amos, Colin P. Thackray, Yanxu Zhang, Elizabeth W. Lundgren, Gael Forget, Carey L. Friedman, Noelle E. Selin, Rainer Lohmann, Elise M. Sunderland

Graduate School of Oceanography Faculty Publications

Human activities have released large quantities of neutral persistent organic pollutants (POPs) that may be biomagnified in food webs and pose health risks to wildlife, particularly top predators. Here we develop a global 3‐D ocean simulation for four polychlorinated biphenyls (PCBs) spanning a range of molecular weights and volatilities to better understand effects of climate‐driven changes in ocean biogeochemistry on the lifetime and distribution of POPs. Observations are most abundant in the Arctic Ocean. There, model results reproduce spatial patterns and magnitudes of measured PCB concentrations. Sorption of PCBs to suspended particles and subsequent burial in benthic marine sediment is …

Trophic Position And Foraging Ecology Of Ross, Weddell, And Crabeater Seals Revealed By Compound-Specific Isotope Analysis, Emily K. Brault, Paul L. Koch, Daniel P. Costa, Matthew D. Mccarthy, Luis A. Hückstädt, Kimberly Goetz, Kelton W. Mcmahon, Michael G. Goebel, Olle Karlsson, Jonas Teilmann, Tero Härkönen, Karin Hårding

Graduate School of Oceanography Faculty Publications

Ross seals Ommatophoca rossii are one of the least studied marine mammals, with little known about their foraging ecology. Research to date using bulk stable isotope analysis suggests that Ross seals have a trophic position intermediate between that of Weddell Leptonychotes weddellii and crabeater Lobodon carcinophaga seals. However, consumer bulk stable isotope values not only reflect trophic dynamics, but also variations in baseline isotope values, which can be substantial. We used compound-specific isotope analysis of amino acids (CSI-AA) to separate isotopic effects of a shifting baseline versus trophic structure on the foraging ecology of these ecologically important Antarctic pinnipeds. We …

Major Shifts In Nutrient And Phytoplankton Dynamics In The North Pacific Subtropical Gyre Over The Last 5000 Years Revealed By High-Resolution Proteinaceous Deep-Sea Coral Δ15N And Δ13C Records, Danielle S. Glynn, Kelton W. Mcmahon, Thomas P. Guilderson, Matthew D. Mccarthy

Graduate School of Oceanography Faculty Publications

The North Pacific Subtropical Gyre (NPSG) is the largest continuous ecosystem on Earth and is a critical component of global oceanic biogeochemical cycling and carbon sequestration. We report here multi-millennial-scale, sub-decadal-resolution records of bulk stable nitrogen (δ¹⁵N) and carbon (δ¹³C) isotope records from proteinaceous deep-sea corals. Data from three Kulamanamana haumeaae specimens from the main Hawaiian Islands extend the coral-based time-series back ∼5000 yrs for the NPSG and bypass constraints of low resolution sediment cores in this oligotrophic ocean region. We interpret these records in terms of shifting biogeochemical cycles and plankton community structure, with a …

The Concept Of Essential Use For Determining When Uses Of Pfass Can Be Phased Out, Ian T. Cousins, Gretta Goldenman, Dorte Herzke, Rainer Lohmann, Mark Miller, Carla A. Ng, Sharyle Patton, Martin Scheringer, Xenia Trier, Lena Vierke, Zhanyun Wang, Jamie C. Dewitt

Graduate School of Oceanography Faculty Publications

Because of the extreme persistence of per- and polyfluoroalkyl substances (PFASs) and their associated risks, the Madrid Statement argues for stopping their use where they are deemed not essential or when safer alternatives exist. To determine when uses of PFASs have an essential function in modern society, and when they do not, is not an easy task. Here, we: (1) develop the concept of “essential use” based on an existing approach described in the Montreal Protocol, (2) apply the concept to various uses of PFASs to determine the feasibility of elimination or substitution of PFASs in each use category, and …

Poly- And Perfluoroalkyl Substances In Seawater And Plankton From The Northwestern Atlantic Margin, Xianming Zhang, Rainer Lohmann, Elsie M. Sunderland

Graduate School of Oceanography Faculty Publications

The ocean is thought to be the terminal sink for poly- and perfluoroalkyl substances (PFAS) that have been produced and released in large quantities for more than 60 years. Regulatory actions have curbed production of legacy compounds such as perfluorooctane sulfonate (PFOS) and perfluorooctanoic acid (PFOA), but impacts of regulations on PFAS releases to the marine environment are poorly understood. Here, we report new data for 21 targeted PFAS in seawater and plankton from the coast, shelf, and slope of the Northwestern Atlantic Ocean. We find strong inverse correlations between salinity and concentrations of most PFAS, indicating that ongoing continental …

Microbial Selection And Survival In Subseafloor Sediment, John B. Kirkpatrick, Emily A. Walsh, Steven D'Hondt

Graduate School of Oceanography Faculty Publications

Many studies have examined relationships of microorganisms to geochemical zones in subseafloor sediment. However, responses to selective pressure and patterns of community succession with sediment depth have rarely been examined. Here we use 16S rDNA sequencing to examine the succession of microbial communities at sites in the Indian Ocean and the Bering Sea. The sediment ranges in depth from 0.16 to 332 m below seafloor and in age from 660 to 1,300,000 years. The majority of subseafloor taxonomic diversity is present in the shallowest depth sampled. The best predictor of sequence presence or absence in the oldest sediment is relative …

The Significance Of Microbial Symbionts In Ecosystem Processes, Roxanne A. Beinart

Graduate School of Oceanography Faculty Publications

It is increasingly accepted that the microbial symbionts of eukaryotes can have profound effects on host ecology and evolution. However, the relative contribution that they make directly to ecosystem processes, like energy and nutrient flows, is less explicitly acknowledged and, in many cases, only poorly constrained. Here, I explore the idea that, in some habitats, host-associated microbes may have an outsized role in ecosystem processes relative to functionally equivalent free-living microbes due to key aspects of the physiology, ecology, and evolution of symbiotic interactions. My research quantifying symbiont metabolism has shown that microbial symbionts have the potential to make a …

Divergent Trophic Responses Of Sympatric Penguin Species To Historic Anthropogenic Exploitation And Recent Climate Change, Kelton Mcmahon, Chantel I. Michelson, Tom Hart, Matthew D. Mccarthy, William P.P. Patterson, Michael J. Polito

Graduate School of Oceanography Faculty Publications

The Southern Ocean is in an era of significant change. Historic overharvesting of marine mammals and recent climatic warming have cascading impacts on resource availability and, in turn, ecosystem structure and function. We examined trophic responses of sympatric chinstrap (Pygoscelis antarctica) and gentoo (Pygoscelis papua) penguins to nearly 100 y of shared environmental change in the Antarctic Peninsula region using compound-specific stable isotope analyses of museum specimens. A century ago, gentoo penguins fed almost exclusively on low-trophic level prey, such as krill, during the peak of historic overexploitation of marine mammals, which was hypothesized to have …

Upper Ocean Distribution Of Glacial Meltwater In The Amundsen Sea, Antarctica, Louise C. Biddle, Brice Loose, Karen J. Heywood

Graduate School of Oceanography Faculty Publications

Pine Island Ice Shelf, in the Amundsen Sea, is losing mass due to increased heat transport by warm ocean water penetrating beneath the ice shelf and causing basal melt. Tracing this warm deep water and the resulting glacial meltwater can identify changes in melt rate and the regions most affected by the increased input of this freshwater. Here, optimum multiparameter analysis is used to deduce glacial meltwater fractions from independent water mass characteristics (standard hydrographic observations, noble gases, and oxygen isotopes), collected during a ship-based campaign in the eastern Amundsen Sea in February–March 2014. Noble gases (neon, argon, krypton, and …

Spatial Variability In Size Structure, Growth, And Recruitment Of Spotted Seatrout Among Six Florida Estuaries, Elizabeth Herdter, Behzad Mahmoudi, Ernst Peebles, Steven A. Murawski

Marine Science Faculty Publications

Spotted Seatrout Cynoscion nebulosus in Florida, USA, are managed under four geographical regions, including Apalachicola Bay and Cedar Key (northwest region), Tampa Bay and Charlotte Harbor (southwest region), northeast Florida (northeast region), and the northern Indian River Lagoon (southeast region). Two of these management regions are composed of more than one major estuary system (northwest and southwest regions). However, previous life history research suggests that the management regions do not accurately reflect the unique biological populations of Spotted Seatrout in Florida. Our objective was to determine (1) whether there is significant spatial variation in size structure, the age–length relationship, and …

Iodp Advances In The Understanding Of Subseafloor Life, Steven D'Hondt, Fumio Inagaki, Beth N. Orcutt, Kai-Uwe Hinrichs

Graduate School of Oceanography Faculty Publications

The most recent decadal phase of scientific ocean drilling through the International Ocean Discovery Program (IODP) has resulted in paradigm-shifting understanding of life below the seafloor. Enabled by new drilling and coring approaches, cutting-edge methodologies, and novel observatory science, IODP expeditions have significantly advanced understanding of the amount and diversity of subseafloor life, the metabolic strategies that this life uses to survive under extreme energy limitation, and consequences of this life for the Earth system. Here, we summarize highlights from recent IODP expeditions focused on life beneath the seafloor and emphasize remaining major science challenges in investigating the form and …

A Direct Comparison Of Biplanar Videoradiography And Optical Motion Capture For Foot And Ankle Kinematics, Sarah E. Kessler, Michael J. Rainbow, Glen A. Lichtwark, Andrew G. Cresswell, Susan E. D'Andrea, Nicolai Konow, Luke A. Kelly

Kinesiology Faculty Publications

Measuring motion of the human foot presents a unique challenge due to the large number of closely packed bones with congruent articulating surfaces. Optical motion capture (OMC) and multi-segment models can be used to infer foot motion, but might be affected by soft tissue artifact (STA). Biplanar videoradiography (BVR) is a relatively new tool that allows direct, non-invasive measurement of bone motion using high-speed, dynamic x-ray images to track individual bones. It is unknown whether OMC and BVR can be used interchangeably to analyse multi-segment foot motion. Therefore, the aim of this study was to determine the agreement in kinematic …

Investigation Of Ccn1 Role(S) In Mantle Cell Lymphoma (Mcl), Afak R S Zaidi

Other Faculty of Health Theses

Mantle Cell Lymphoma (MCL) is a comparatively rare non-Hodgkin`s lymphoma which is characterised by the overexpression of cyclin D1. Many patients present with or progress to advanced stage disease within three years. Disease progression involves down regulation of cyclin D1. Moreover, MCL is broadly considered as an incurable disease with median survival of patients being 3-4 years. CCN1, a matricellular protein involved in stem cell signalling within the haematopoietic microenvironment is highly expressed in early stage MCL cells and down-regulated in advanced stage disease. We have used the human MCL cell lines REC1

An Exploration Of Sharps Injuries Within A Nursing Student Population In The Uk, Kevin Hambridge

Other Faculty of Health Theses

Percutaneous injuries, such as sharps injuries, can transmit up to 60 different types of pathogen (Tarantola et al., 2006) to the injured party. Whilst up to 100% of some nursing student populations sustain sharps injuries (Trivedi et al., 2013), a dearth of research studies investigating the topic worldwide exist. It is unknown within the UK the devices contributing to sharps injuries, the incidence rates and the locations where they occur. The aims of this study were to identify the characteristics of sharps injuries within a nursing student population within the UK; to explore the experience of sharps injuries, concentrating on …
